Syringe-filling and medication mixing dispenser

A medication dispenser, for use with a first container containing a first, liquid pharmaceutical, a second container containing a second pharmaceutical and a syringe of the type including a needle cannula, a barrel and a plunger, the dispenser comprising:

• a body to which the containers and the syringe are mountable;
• dual port means for providing first and second gas and liquid ports into the interiors of the first and second containers;
• a first passageway fluidly connecting the first and second liquid ports to permit fluid flow from the first container to the second container but not flow in the reverse direction;
• first means for pumping the first liquid pharmaceutical into the second container through the first and second liquid ports along the first passageway so the pumped first pharmaceutical mixes with the second pharmaceutical in the second container to create a first mixed liquid pharmaceutical while gasses pass into the first container and out of the second container through the first and second gas ports, respectively;
• second means for pumping the first mixed liquid pharmaceutical from the second container through the second liquid port while replacing the first mixed pharmaceutical with gas which passes into the second container through the second gas port;
• and
• means for fluidly directing the first mixed pharmaceutical from the second liquid port to the needle cannula;
• whereby the mixed pharmaceutical is pumped from the second container by the second pumping means, through the needle cannula and into the syringe.

A medication dispenser, for use with a first container containing a first, liquid pharmaceutical, a second container containing a second pharmaceutical, a third container containing a third, liquid pharmaceutical and a syringe of the type including a needle cannula, a barrel and a plunger, the dispenser comprising:

• a body to which the containers and the syringe are mountable;
• dual port means for providing first, second and third gas and liquid ports into the interiors of the first, second and third containers;
• a first passageway fluidly connecting the first and second liquid ports to permit fluid flow from the first container to the second container but not flow in the reverse direction;
• first means for pumping the first liquid pharmaceutical into the second container through the first and second liquid ports along the first passageway so the pumped first pharmaceutical mixes with the second pharmaceutical in the second container to create a first mixed liquid pharmaceutical while gasses pass into the first container and out of the second container through the first and second gas ports, respectively;
• second means for pumping the first mixed liquid pharmaceutical from the second container through the second liquid port and the third, liquid pharmaceutical from the third container through the third liquid port while replacing the first mixed and third pharmaceuticals with gasses which pass into the second and third containers through the second and third gas ports;
• and
• means for fluidly directing the first mixed and third pharmaceuticals from the second and third liquid ports to the needle cannula;
• whereby the mixed and third pharmaceuticals are pumped from the second and third containers by the second and third pumping means, through the needle cannula and into the syringe.
